The aim of this study was to evaluate the effect of vitamin C supplementation in mid-laying Japanese quail on productive performance and egg quality. Eighty quails of 23 weeks of age initiating the second third of laying were used. The birds were housed in 20 cages (four birds per cage) and distributed in a completely randomized design with four levels of inclusion of vitamin C in the basal diet: 0, 100, 200 and 300 mg of vitamin C per 100 kg of feed. As productive performance, the feed intake (g/bird/day), laying percentage and feed conversion were determined. Additionally, the weight, height and length of the egg, the height and weight of the yolk and the albumin, and shell thickness were measured as egg quality variables. Vitamin C supplementation at increasing levels in the diet of quails had no effect on productive performance and egg quality, except on shell thickness (p<0.05).

El presente trabajo de investigación se desarrolló en base a la utilización de la Vitamina C en la alimentación de codornices (Coturnix coturnix japonica) en postura criadas en ambiente tropical y cuyo objetivo fue evaluar su efecto sobre el desempeño y calidad de huevo, realizada en la Universidad del Estado de Mato Grosso – UNEMAT – Ciudad de Pontes e Lacerda – Brasil en el año 2013. Se evaluaron 4 raciones experimentales con inclusión de los niveles de 0; 100; 200; y 300 mg. En el estudio se emplearon 80 codornices japonesas de 23 semanas (161 días) de edad, distribuidos al azar, con 4 tratamientos y 5 repeticiones (20 codornices por tratamiento) y un grado de confiabilidad (P<0.05). El periodo de experimentación tuvo una duración de 28 días. La estadística inferencial se realizó por medio del diseño completamente al azar y la prueba de Tukey para la comparación d...
